magento2: msrp module error breaks the swatches on product configuration page

Preconditions (*)

1. Magento 2.3.1 Theme Luma
2. Msrp module is disabled

Steps to reproduce (*)

1. Add a configurable product
2. Create a configurations for product:

• add two new attributes: color swatch + text swatch
• add separate pictures eg. for color variants
• apply same price to all skus
• apply same quantity to all skus

1. Go to created product’s pdp, select color swatch + text swatch and add it to cart
2. Open minicart and click “edit” button to go to product configuration page

Expected result (*)

1. Previously selected configuration should be saved and swatches should be selected
2. Click on the swatch should change the product image (if configured)

Actual result (*)

In console there is an msrp module error which breaks the swatches functionallity:

• preselection of previously selected configuration does not work
• if you configured swatches to change product gallery - this stops working, too

Here is the error that appears:

And form my investigation, error is triggered in swatches-renderer.js OnClick method, where below logic triggers the “updateMsrpPriceBlock” event:

$(document).trigger('updateMsrpPriceBlock',
    [
        parseInt($this.attr('index'), 10) + 1,
        $widget.options.jsonConfig.optionPrices
]);

On regular PDP, msrp module does not listen to this event, while on product configuration page it does - even if msrp is disabled. Either msrt should not listen here, too or wrong data is passed to this event and it breaks.
